Web Application ArchitectureWhat is a container? The servlet does not have a main () method. They are controlled by another Java application, a Java application called a container.Tomcat is such a container. If a Web server application (such as Apache) gets a request to a servlet (as opposed to another request, such as requesting a normal static HTML page), the server does not hand the request to the servle

Starting from the early stages of the network, it is hoped that their Web servers will not only be able to display static documents, but that the Universal Gateway Interface (CGI) extends the capabilities of the server, but at the expense of additional processing processes. FASTCGI integrates the external CGI processing process more closely with the Web server, and for proprietary server APIs such as NSAPI and ISAPI, they integrate the external process directly into the server as a server plug-i

First, Servlet1, understanding servletServlet (Server Applet), full name Java Servlet, without Chinese translation. is a server-side program written in Java. Its main function is to interactively browse and modify data to generate dynamic Web content. The narrow-sense servlet refers to the Java language implementation of an interface, the generalized servlet refe

the Web program is powerful. An application, no installation, just a browser, you can do your own thing. Convenient, fast, clean and environmentally friendly. This is the current stage of understanding of it.The previous article was vulgar about Java-related containers, in which the Java architecture-related container of a web container is the core of web development, is the servlet,

The servlet servlet API has long been the cornerstone of enterprise application development, while servlet filters are a relatively new complement to the Java family. This article introduces you to the Servlet filter architecture, defines many of the filters ' applications, and guides you through the three steps of a typical filter implementation. This article also reveals some of the exciting changes in the bean, which are expected to be introduced i

Third, The life cycle of the ServletA Java servlet has a life cycle that defines how a servlet is loaded and initialized, how it receives a request and responds to the request, and how it is purged from the service. the life cycle of the Servlet is defined by the javax.servlet.Servlet interface. all java Servlet javax.servlet.servlet interface so that it can be in a servlet run in the engine. servl
